HKS Grommet Type Head Gasket 1.2 mm Toyota FA20 (89.5 mm bore) - 23002-AT002

Grommet type head gasket, 1.2 mm thick, for turbocharged and supercharged FA20 engines.

• Grommet structure keeps gasket seal surface pressure up, raising the seal limit; works best with strengthened head bolts
• 1.2 mm thickness gives compression ratio 10.4 with the HKS FA20 2.1L Kit Low Comp (21004-AT003); the 0.8 mm gasket gives 10.8 (design calculation values)
• Stock gasket is 0.6 mm, compression ratio 12.5
• High surface pressure can warp the block or heads; the thicker option helps compensate for head and block machining
• Bore 89.5 mm

Fits:

• Toyota FA20 engine, 89.5 mm bore (HKS Japan)
